Straighteners at the ready...
We all love a good hair makeover. For some, it's a post-break-up revamp and for others, it's just a bi-annual style update. Either way, celebrity hair transformations are pretty much essential to our general well-being.
Kim Kardashian has been donning some seriously poker straight long locks of late (see below) but it looks like she's gone for the chop again.
Having debuted her bob hairstyle earlier this month with a wet look hair vibe, the reality TV star showed off her short hair, don't care, in all its glory at The Promise film premiere last night.
Kristen Stewart is another star to completely change up her hair, debuting a new blonde, shaved style at the Los Angeles film premiere of Personal Shopper. It's safe to say that it looks totally different from her previous short brunette style.
Katy Perry is another star who recently underwent a dramatic hair makeover, chopping off her locks just days after it was announced that she had broken up with her boyfriend of over a year, Orlando Bloom.
Just this morning she posted a couple of video clips of her new look to her Instagram feed, and understandably, the world is going crazy for it.
Katy's not the only celebrity to give us some serious hair inspiration.
Whether you're searching for a bit of inspiration for something new, or you're just imagining life in a different shade, check out our favourite celebrity hair transformations and makeovers past and present for some ideas. And, if you want to get your hair in tip-top condition, take this quiz to find out which conditioner you should be using for your hair type...
Who does it best?
Possibly the most dramatic of these celebrity hair makeovers are sported by the likes of Lily Allen, Kylie Jenner and Rita Ora. All style chameleons in their own right, these hair provocateurs love to play around with crazy hues and exciting cuts. Somehow, they manage to make it look oh-so-effortless too. Who can pull off wild things like the colourful sea-punk trend? Them.
And few can do rainbow hair better than queen Kylie Jenner herself. Her ever changing assortment of candy-coloured wigs have set the standard for multi-coloured hair. Both in the fashion world and beyond. Kylie's own line of hair extensions and her fearless sense of style have well and truly cemented her position as a global hair-goddess. And her best mate, Gigi Hadid, has definitely taken on some of her hairstyle tips. They actually give us the confidence to pull off blue hair. Sure, we're yet to actually do it, but the thought is there.
There's also J.Lo who has swapped between flowing, ombre curls to sleek, dark new 'dos. Lily James regularly flicks between her Cinderella-esque style and natural colour and shorter length. And Sienna Miller, who went from her signature blonde bob to a smokey shade of red, recently went back to blonde again. Although these stars haven't opted for bright colours, they've still undergone pretty drastic makeovers. And as always, they've still managed to look amazing in the process. Granted you can pull pretty much anything off with a hot team of hair experts on hand. But, even if you are lacking in a glam-squad, our gallery will guide you to your next ultimate hair makeover.
